I'm an Academy of Finland Fellow at the
University of Helsinki
in the
Department of Computer Science
and a member of the
Genome Scale Algorithmics and the
Practical Algorithms and Data Structures on Strings groups.
Prior to that I was a Newton Fellow in the Algorithms and Bioinformatics group
at
King's College London, and earlier
still I held an Australian Postdoctoral Fellowship in the Search Engine Group
at
RMIT.
My current research focuses on efficient
algorithms and data structures for searching, storing, and manipulating strings, trees and graphs,
and applications thereof (like bioinformatics, information retrieval, database systems, and data mining).
I obtained my PhD from Curtin University, Western Australia, under the supervision of
Bill Smyth and
Andrew Turpin.
